CAST-STEEL TRUCK;

Specification of Letters Patent.

Patented Jan. 21, 1908.

Application led September 20, 1906- Serial No. 335.413.

To all whom it may concern:

Be it known that I, WILSON E. SYMoN-s,

v'la citizen4 of the United States, residing at Chicago, in the county of Cook and State of fication.

Illinois, have invented a new and useful Cast Steel Truck', of which the following is a speci- This invention relates to a novel castv steel y truck,l designed more particularly for use in connection with cars and locomotive tenders. The constant increase in the weight of both tenders -andcars of certain types, as for instance furniture, ballast,'circu s, and other cars, together with the enlarged dimensions thereof, make it desirable to provide trucks thereforwhich will allow the car bodies t'o be located very low or near the track. It has therefore been proposed to utilize a low archbar type of truck with the straight bar en top, the offset being below the plane in-which the upper sides of the oil'boxes `are located. This arrangement, however, adds materially to the undesirable features of the ordinary arch-bar truck, particularly as to the key bolts, the

ends of which are necessarily located sonear the rail ,that interference with switch rails, guard rails, frogs, road crossings, and other parts of the superstructureor permanent way is made possible, f

As distinguished from this proposed use of the'ordinary arch-bar type of truck, the object of my invention isto produce a cast steel truck in which practically the entire truck structure will be located in a plane belowl that ofthe upper sides of the oil boxes, and in which the column bolts, nuts, and other downwardly projecting portions, which might interfere with any` portion of the permanent Another object is to so, construct the cast steel side members of the truck that the former, while being capable of sustaining an enormous weight, 'will be of extremely light and inexpensive construction.

A further object ofthe invention is to provide a novelconnection between the side members, saidconnection being suliciently.

elastic to absorb .the strains imposed upon thetruckby irregularities .of the road-bed and including angle bars extended into cored out sockets or seats formedfin the side members.

Another object ofthe invention is to insure the retention of the side frames in proper vertical position and the proper relative positions ofthe side frames and bolster, by pro- V viding the latter,nadjacent to each end thereof, with inner and outer guide lugs disposed at opposite sides of the top bar ofthe side mem# ber and with safety guides located at the inner and outer side of each vertical strut of theI side member.

Another obj-ect ofthe invention, subordi-` nate to that just stated, is to provide the-side member with detachable shoes, which, whenin place upon the vertical struts, will coperate with thesafety guides of the bolster and lock the same in the side frames, but which, when removed, will permit the displacement of the bolster to facilitate repairs.-

Various other objects, and additional structural characteristics, will hereinafter appear as the description of the illustrated embodiment of the invention is developed.

. In the accompanying .drawings-Figure 1 is a sectional plan view of my truck complete, one side bein shown in plan and the other in section. ig. 2 is a side elevation ofthe truck.l Fig. 3 lis an elevation of one of the side members detached. Fig. 4 is an end view of the truck. Fig. 5 is a vertical Isection through one of the side frames and the adjacent end of the bolster, and Fig. 5 is a detail view ofone of the shoes.

1-1 indicate the side frames, 2-2 the cross members, 3 the bolster, which supports the vehicle. body, 4 the axles, 5 the oil boxes, supported by' the axles 4 and in turn sup porting the side members 1, and 6 the wheels fixed to and rotatably supporting the axles 4. A As best shown in Fig. 3, each side member 1 comprises spaced top and bottom bars 7 and 8, intermediate of which are vertical struts 9, `10, 11 and 12. The central struts 10 and 11 define between them a central opening 13 and thelend struts 9 and 10 are located a sufficient distance from the outer ends ofthe upper and lower bars 7 and 8 to define open jaws or oil box receptacles 14 and' 15 within which the oil boxes 5 are received and retained by tapered keys .16 located at the outer sides of fthe boxes and passed through the upper and lower jaws of the receptacles, as shown inl Figs. 1 and 2. The spaces between each central strut and the adjacent end strut is occupied by a web 17 designed to lend rigidity to the structure and out out for the sake of lightness. The cut out portions of the Webs 17 are so arranged that curved brace members 18, extending between the upper and lower members, are produced adjacent to the end struts 12 so asto form`4 a substantial backing f\ for Athe abutments with which the linner ment.

vhave made provision for the attachment of '1 these chains and in so doing have provided "sides of the oil boxes engage.` 'i noted also that the ,lower bar 8 of the side" thusI lendin It Will be member extends .in a graceful downward cutve between the inner tlower corners of the oil box receptaclesand that belowfthe bar is droppedma"substantiallintegral fin lor'flange 19 which gradually tapers from theniiddle of theI side member to the opposite ends thereof, great rigidity to that-portion of the side frame upon which the weight vof the car is imposed. Y

It is usual in truck constructions, particularly in those designed for the support of locomotive tenders, to attach what are called check or safety chains, which connect the corners of the truck frame with the body of the tender for the y purpose of preventing the-truck from turning in the event of derail- In my improved construction, I

an excess of metal at'those points yat which the upper bar'of thetruck is subjectedl to the greatest strain, to-wit7 fat the j'unctures of the upperv bars '7' withj the vertical end members 9 and 12. It willbe notedby i reference to Figs. l, 2 and 3 that upwardly extending safety chain'y lugs 20 l are cast integral with` theupper'bar'7 of each side frame substantially opposite the upper inner Acorners of the oil box receptacles and prefpleasing contour, since the upper bar, whilel straight as a'matter of fact, is given a general drop-center appearance correspond* ing, approximately to the appearance of the lower bar, sol that the side member or frame as a' wholel appearsto have a'longitudinal `curve giving a graceful fdownward sweep at 7 the center thereof. y

The lower portions of the central struts 10 and 11 are considerably wi'dened, as. indicated at 24, and are extended both inwardly and outwardly from the side frame to form inner and outer. extensions 25 and 26 thereof. Said extensions also include a 'transverse' member 27, located in a plane abovevthe upper edge of the lower bar 8 and extended between the outer ends of the extensions-25 and 26. The member .27 is integral with the struts 10 and 11, andl is spaced from the top of the lower member 8 to define the hori- .thrust la zontal portions of angular seats 28 vthe ve'rtiv cal portions of which are formed` in 'the widened lower ends ,of the struts,l see Fig.

3. These angular seats 28 are designed for the reception of the cross members 2 which arein l the 'form of angle bars having their f louter ends extended through the side niembers and located withintheseats 2SJ it being understood that the angular seats which receive the angle bars extend entirely through the side members and are preferably formed by cores during the casting thereof.

The manner of securingthe angle bars in A the angular seats -or openings of the side members is not material, since keys,rivets, or other suitable securing means 'may be provided for this purpose. I prefer, however, to rivet the horizontal flanges 2 of the cross members 2 to the inner and uter ends of the Itransverse member or platform 27, asby rivets 29, and to similarly secure the vertical flanges 2a'. of the sidel members to the extensions 25 and 26 of the'struts, as by rivets 30,

see Fig' 1.v The platform 2,7 is also designed to'serve as a spring seat and forthis purpose its upper surface is formed for the `reception of the bolster supporting springs 31,*portions of the latform being cut out, asshown in Fig. 1,' 0r thesake. of lightness.` It will also be noted, by reference to Fig. 2, that since the angular seats or openings 2S are spaced apart, 4the Iintervening metal constitutes a support 32 for the central portion of -that partof the platform 27 which constitutes the seat for the springs, thus lending great rigidity to the'structu're.' It will be 4seenV that this manner of. connecting the transverse members of the `truck with the side members thereof affords an extended bearing for the former, and while permitting the flexibility of the crossmembers to ab in the-injury of the truck structure, prevents greater relative movement of thepartsthan is necessary for the) accomplishment of that purpose. x y

, The bolster 3 is locatedabove the hori# z'ontal flanges 2 of the cross 'members and side members, as shown in. Fig. 5,'being provided with'` integral sprin seats- 33'iwhich restupon the upper ends Ao the springs'S l. in a manner well understood in the art. At each endof the bolster and' projecting up,- Wardly therefrom are a pair of thrust flanges 34 and 35 located respectively at the'outer and inner sides of the adjacent side member and arranged to cooperate with the opposite sidesof the u per bar 7 thereof, see Fig. V5. These thrust anges serve to prevent the ap proachor recession of the upper edges of the side members and guide the bolster in. its vertical movement: l l In additionto the what mayl e A`termed safety guides whereby es, hoWever,tI prefer to employ.

ico

its

sorb all torsional strains which could result iio extends' through thefcentral openings in the v i lflfl the bolster will still be properly guided in its i movement and4 the relation of the" bolster and side frames retained, in the event of breaking of/on'e or'more of the thrust flanges. At-tlie oppbsitel sides of each end of the bolster aref "'or'ned vertically-disposed safety /which may be produced by yforming t-rtic'al recesses or vertical flanges in or uponithesides of the bolster when the latter is cast. These guides receive and slide vertically upon a pair of shoes 37 imposed against the inner faces of the struts l0 and 4l1 and provided with side flanges 38 which bear against lthe opposite edges of the struts 'and serve t0 prevent the displacement. of the Obviously, these-shoes 37 not only serve tor guide the bolster, but constitute keys which interlock the bolster with the side frames and thus prevent dislocation of the sidev members even in the event of the breaking of the thrust flanges. l

It is thought thatv from the foregoing the novel construction of my truck and the many advantages accruing from the use thereof will be clearly comprehended. However, I do not wish to be understood as limiting myself to the structural details defined, as on the contrary, I reserve the right to e'ectsuch changes, modifications, and variations of the illustrated structure as may come fairly within the scope of the protection prayed.
